abrupt wave 中文意思是什麼
abrupt wave
解釋
陡浪-
This isi series oscillation has following characters : ( 1 ) long term cycle duration, whose duration of most oscillations ranged from 3 0 - 120ms, so we called it slow wave oscillation ; ( 2 ) large amplitude of oscillation, the minimum isi is about 2ms while the maximum is beyond 40ms, which suggested that the firing frequency vary from several tens to hundred hz ; ( 3 ) abrupt turn always occurs during the continuous change in isi, this turn is called inflexion temporarily
該振蕩波有下述特徵： （ 1 ）振蕩周期較長，多數在30 ? 120s范圍，故稱慢波振蕩； （ 2 ）振蕩幅度較大，其isi振蕩最小值在zms左右，最大值可達40ms ，表明放電頻率可在幾十到幾百k范圍內變動； （ 3 ）在isi連續變化過程中往往出現突然轉折，暫稱其為拐點。 -
Abstract : the propagation of waves passing over the abrupt changing topograghy can be simplified as a wave passing over a step. this flow process can be reasonably simulated by a 2 - d numerical wave flume developed in this paper, especially for the nonlinear transformation of the wave on the step. numerical results have been verified by experimental data
文摘:波浪在水深劇變地形上的傳播，可以簡化為波浪在臺階地形上的傳播.利用二維數值波浪水槽可以很好地模擬這一過程，特別是對波浪在臺階上的非線性變形.數值計算結果與實驗測量進行了比較，結果吻合良好 -
The paper did scrupulous discussion and investigation on the interaction between electron beam and standing wave field in the gyroklystron, which is typical in the electron cyclotron maser which action rf system is resonant cavity. the main works of this dissertation are listed as following : first, solving field in absorbing material and field matching method were used to derive the dispersion equation in waveguides and field matching formulas of hybrid modes in an abrupt cavity with absorber. based on the theoretical analysis, numerical simulations of the cavities in gyroklystron were done
主要工作有:一、採用吸收介質分區求解及場匹配的方法推導出含有吸收層的色散方程，單側加入吸收介質及兩側均加入吸收介質兩種突變結構混合模場的匹配方程，在理論分析的基礎上，通過相關的模擬軟體，建立了迴旋速調管介質加載中間腔的計算模型，對迴旋速調管中間腔進行了數值模擬，並給出了主要的計算結果。
